A chemist designs a galvanic cell that uses these two half-reactions: half-reaction standard reduction potential Cro (aq)+4 H₂O(+3e" ->>> Cr(OH)3(s)+ 5 OH (aq) red -0.13 V E red +1.065 V Br₂(1)+2e → 2 Br (aq) Answer the following questions about this cell. Write a balanced equation for the half-reaction that ☐ happens at the cathode. Write a balanced equation for the half-reaction that happens at the anode. Write a balanced equation for the overall reaction that powers the cell. Be sure the reaction is spontaneous as written. ☐ Do you have enough Yes information to calculate the cell voltage under standard No conditions? If you said it was possible to calculate the cell voltage, do so and enter your answer here. Round your answer to 3 significant digits. Ον ローロ X G
